The SNMP dissector fails when a MacAddress is part of the instance index for an
OID.

The error produced is:
Dissector bug, protocol SNMP, in packet 1: proto.c:1405: failed assertion
"hfinfo->type == FT_BYTES"

The packet in question is from the Q-BRIDGE-MIB.
The packet capture "test.pkt" was created by walking the dot1qTpFdbTable and
then the dot1dTpFdbTable.
